Furthermore, the two rollers of the roller assembly are completely identical in shape and are arranged on the skew rolling mill in a left-right parallel mode.

Furthermore, the number of the spiral semicircular rolling grooves on the roller body of the roller is 3, which is favorable for better molding of the wear-resistant steel balls.

Furthermore, the roller cooling water pipe is arranged at the top of the inclined rolling mill frame, and the roller cooling water pipe can also penetrate through a through hole arranged on the inclined rolling mill frame and is arranged above the roller, so that the roller is cooled when rolling a steel ball, and the service life of the roller is prolonged.

Furthermore, the two roller cooling water pipes are arranged above the roller cooling water pipes in parallel relative to the roller.

The utility model discloses a roll subassembly working process does: the spiral semicircular grooves on the two roller bodies of the rollers oppositely form round holes, a rolled piece advances along with the spiral rotation of the rollers, the rolled piece is sheared by the roller cutters, the rolled piece gradually becomes spherical along with the rotation of the round holes formed by the grooves, the connection part between the spheres gradually becomes thin, and finally the steel balls are obtained by breaking.

The utility model has the advantages that: the steel ball is rolled by the roller with the gradually deepened rolling groove, the shape of the obtained steel ball is more round, the surface of the steel ball is relatively smoother, and the grinding effect of the steel ball is enhanced; the roller cooling water pipe is added, so that the roller can be cooled, and the service life of the roller is prolonged. The utility model discloses simple structure, production efficiency is high, can effectual reduction in production cost.
